IMPROVEMENT IN HORSESHOES.

Specification forming part of Letters Patent No. 8l, 142, dated August 18, 1868.

To all whom 'it may concern:

Be it known that I, J oHN N. CLARKE, of the city of Cincinnati, county of Hamilton, and State of Ohio, have invented a new and useful Improvement in Detachable Calks for Horseshoes and do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

This invention relates to a simple and secure method of attaching calks to horseshoes, and the device is susceptible of adjustment, so as to permit of its being applied to shoes of various sizes.

In the accompanying drawings, Figure l is a perspective view of the under side of an ordinary horseshoe with my calks attached thereto, and Fig. 2 is a transverse section of the same.

The plate or slipper A, which is of the usual form, has my detachable'calks secured to it in the following manner: B and C are two flat bars, which curve inward toward the center of the shoe, at which point they are united by a screw, D, that passes through both of said bars. The front and rear ends of these bars are provided with downwardly-proj ecting calks b b and c c', the ones b c being near the toe, and the ones b c near the heel, of the shoe.

The ends of the bars B C terminate in upturned clips E, which embrace the sides of the shoe and the lower portion of the horses hoof; and, if preferred, these clips may be provided with inwardly-projecting spurs G, so as to effect a more secure and perfect attachment to the hoof. v

In the drawings the device is shown as ap plied to a dat plate or slipper 5 but it is evident that it can as readily be attached to a shoe having the usual heel and toe projections.

It will be seen that these calks can be attached to a wider shoe than the one illustrated by simply unslacking the screw D, so as to separate the bars B C a greater distance 5 butin case the shoe should be longer than the one shown, it Vwill be necessary to use an attach. ment in which the bars are somewhat longer.

In manufacturing these articles they will be made of different lengths, so as to suit every size of shoe.

It will be seen that this attachment is very simple in its construction, and that it can be applied to any shoe in a few moments, and, when once secured in position, it cannot be accidentally displaced.

I claim herein as new and of my invention- The detachable calk for horseshoes, consisting of the inwardly-curved bars B C, calks b b c c, retaining-screw D, and clips E, either with or without the spurs e, substantially as herein described and set forth.

In testimony of which invention I hereunto set my hand.
